Abstract
Abstract A pair of sliders to be arranged reversely to each other on a pair of fastener stringers so as to be padlocked together in abutting engagement with each other upon full closure of the fastener. Each slider has a forwardly projecting link portion formed on the front end of its body and having an eye formed transversely therethrough. On one of the side faces of the link portion there is formed a forwardly directed ledge extending radially or diametrically of the eye. Upon full closure of the fastener, the link portions of the two sliders interlock, with their opposed ledges in close contact with each other, to hold their eyes in axial alignment for the insertion of the padlock shackle. The link portion of each slider has its bottom end formed into a tongue which can be received in a groove formed in the body of the other slider.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
A slider for a slide fastener which slider is disposed to be locked together with an oppositely facing similar slider on the same slider fastener, which slider comprises: (a) a body having a pair of wings connected to each other at corresponding ends by a neck to define a Y-shaped guide channel therebetween for passage therethrough of fastener element rows of the slide fastener; (b) a link carried by one of said wings and having an eye extending transversely through the link to accommodate the insertion of a locking means, said link extending beyond the end of said slider and generally parallel to the longitudinal axis of said slider, said link having on one side a ledge extending radially of said eye generally perpendicular to said one wing, said ledge being positioned for abutment with the ledge of said similar slider to position the eyes of both sliders in alignment to receive through both eyes said locking means and to prevent pivotal movement of said sliders relative to each other when locked together by said locking means received through said both eyes.
Claim 2
Dependent Claim
